Corinthians 19:9

For though I am free from all, I have made myself a servant to all, that I might win more of them. 1 Corinthians 9:19 (ESV)

One of the most impactful stories I have ever heard was about two co-workers, Jim, a believer, and Carl, an unbeliever. They talked often at work but didn't have much of a relationship outside of the office. One day, Carl came into work looking upset and discouraged so Jim asked him what was wrong. He explained a little bit about his troubles with his wife and kids and his anger issues. Jim turned to him and said, "Well Carl, why don't you come to church with me this Sunday morning. It might help!" Carl stared blankly at his coworker and asked, "Why would I want my life to be anything like yours?"
When I first heard this story it was like a punch in the gut. I was so convicted by it. I knew I was just like Jim. A church goer on Sunday but what did I have to show for it all the other days of the week? Road rage, gossiping, bad language, negativity, fear, shallowness. That is what I had to show for myself anywhere but church. Why would anyone want to go to church with me?
This verse never fails to remind me of that story and how my witness is quickly ruined when I act in those terrible ways. I can't be perfect, and I never will be, but I should always attempt to live my life in a way that, "might win more of them." I should serve others in a way that makes them wonder what I have that makes me different. Wonder what makes me joyful, loving, patient, gentle, and so on.
